There’s a time and a place for the kinds of deep conversations that put an end to the giggles and change the mood of the whole evening. Your troubled past, your confessions, your worries and so on and so forth – all very valid when the time is right. By contrast, bring all this crap up at the height of the good times during the session and you’ll just wreck everyone’s buzz. And do it on a frequent basis and you can expect your invites to suddenly start getting ‘lost in the post’ as it were.
